On Building a Pedalboard for My Acoustic Guitars

At Dave’s Guitars, the Acoustic Room Manager

Late last year 2021, I was at Dave’s Guitars in LaCrosse, WI and it was there that I acquired my first Collings acoustic, a 0002H. Since I perform monthly live at an Open Mic Night that I host with a friend, and because I like to play through an acoustic amp when I play at home, I requested that the shop install a pick up in the guitar before I headed back home to Iowa.

K&K Pure Mini Pickup

The gentleman who manages the acoustic guitar department was emphatic that the best pickup for a Collings acoustic guitar was the K&K Pure Mini because it was generally transparent sounding, way less prone to feedback, and relatively easy to install.

L.R. Baggs Venue DI with tone controls and tuner

A challenge with a passive pickup like the K&K Pure Mini is the absence of a preamp/equalizer to control guitar tonality, such as bass, mids and treble, as well as to boost the signal. My previous acoustic guitars were Taylors which had a preamp/equalizer and pickup installed as part of the guitar itself, so I was at a bit of a loss, until my Dave’s guy suggested that I should also purchase a DI/Preamp with built in equalizer to manage the pickup, and he recommended the L.R. Baggs Venue for the job. When I suggested that I already owned a rather extensive pedalboard that I used with my electric guitars which might accomplish the same thing, he visibly shuddered and said he would never, ever run a Collings acoustic guitar through those electronics. It would be a major compromise to the guitar’s tone, which is what Collings guitars were all about!

At a gig with the Venue DI & 0002H

So, I ordered an L.R. Baggs Venue and put it to good use when I played a gig at one of our local coffee shops. The 0002H was cabled into the Venue which was then cabled into a Bose T4s Mixer and then on into a Bose L1 Pro PA and it worked well enough.

Still, I was unsure whether or not I had the best possible tool kit at my disposal for projecting the best possible tone from my Collings. Consequently, I started digging around the internet and discovered that the L.R. Baggs Company in the past few years has developed a line of pedals that were specifically attuned to the unique complexities and frequencies of acoustic guitars. They’re referred to as the Align series of acoustic pedals, and include a compressor, a DI, an equalizer, a reverb, a delay, and a chorus.

L.R. Baggs Session Compressor Pedal

In my judgement an essential pedal for all amplified guitars is a compressor, because to me it makes the guitar sound better. Most importantly the compressor levels the dynamics of different strings, which can be very helpful in making the guitarist sound more pleasant, especially when playing fingerstyle. As you can see on the right, the L.R. Baggs compressor has a simple layout with volume and gain controls at the top. I use just enough gain to keep the signal flowing through the chain as I don’t want gain fattening up the signal beyond what I perceive to be a natural acoustic tone. The various pedals in the signal chain all have some form of volume control, some of which alter the guitar’s overall dry signal and other control the loudness of the effect the pedal was designed for. I tend to keep the loudness/volume controls set close to mid-point and do final volume control at the Venue DI or the Amp/PA. The effects volume is set to keep the effect subtle and not to overwhelm the guitar’s dry signal.

The Compressor’s saturate knob can “enrich” the tone, but with a Collings I don’t find that a necessity, so I keep it tuned down so as not to affect the natural brilliance built into the guitar. Where the “rubber meets the road” is the comp eq knob and here is where the guitar tonal dynamics are controlled. What I do is adjust the knob, and then back and forth mute or activate the combined Session compressor and Venue DI so that I eventually get the natural sound of the guitar unplugged but simply louder when the signal chain is engaged, and “By-Jiminy” it works!

In truth, the combination of the Venue DI and Session Compressor would be enough if all you wanted during a performance was the natural sound of the guitar amplified. During the time that I possessed just those two pedals I ran them in series with the guitar into the compressor, then feeding directly into the Venue. When I used the chromatic tuner that is built into the Venue, I would turn the compressor off before hand so that a clean signal reached the tuner.

L.R. Baggs Reverb

The fact is, sometimes I like to use tone modulation pedals in very light doses to add mood or flavor to the guitar’s basic tone. Consequently, I anticipated eventually adding the L.R. Baggs Reverb and Delay pedals to the signal chain. I sold some old pedals I was not using and purchased the Reverb first.

Again, as with the Compressor, the control knobs for the Reverb are fairly simple. No choices of multiple types of Reverb are available as typical on pedals such as those manufactured by Boss or Neunaber. L.R. Baggs engineered a Reverb signal they thought best complemented an acoustic guitar, and I like it. In the case of this Reverb pedal, the volume and tone controls just alter the reverb effect and not the guitar’s dry signal. Also onboard are knobs to adjust the amount of reverb and the decay, which is the duration of the effect. As I said before, with an acoustic guitar like a Collings, if I engage reverb, I like to do it with subtlety.

FX Loop Input/Output in rear of Venue DI

After studying the L.R. Baggs Venue literature, I decided to reroute my pedals from a straight line configuration, meaning they connect to each other train car style, one after the other, until they reach the Venue as last entry point. Instead, I chose to use the Venue’s EFX loop with input and output jacks located in the back of the device. Basically the Compressor and Reverb pedals are lassoed together and run via a cabled loop into and out of the Venue’s rear. As I understand it, the native signal from a guitar’s passive pickup, such as my K&K Pure Mini, is not particularly strong. Consequently, it is prudent to use effects pedals after the guitar’s signal is strengthened by the Venue’s Preamp. Theoretically, this results in a cleaner signal for the pedals to manipulate, giving precise and more audibly pleasing control over the effects. Effects such as Reverb and Delay would clearly benefit from flowing through the EFX loop. Whether or not the Compressor belongs in the EFX loop or is instead located before the preamp can be debated; however, I have it located in the loop and it sounds just fine to me.

L.R. Baggs Delay

I completed the signal modulation section of my acoustic pedalboard with the acquisition of the L.R. Baggs Align Delay pedal. This pedal too is tied into the EFX loop and I tend to set it to give a subtle slapback effect, which, when used adds some further depth to the guitar’s tonality. To maintain subtlety, I limit the delay time with the delay knob, limit the number of repeats per unit time and keep the time of the delay relatively brief. The tone knob controls the brightness or darkness of the delay effect and I tend to keep that setting relatively neutral.

It is apparent via this discussion that I tend to use modulation and compression pedals in this configuration in a “set it and forget it” mode. I don’t like fiddling about with the pedals especially when performing. On the other hand, I do have separate Venue DI equalizer settings depending on which guitar I am using. I keep a photograph of the settings for the 0002H and the C10-35 on my iPad, and can easily adjust if I switch guitars when playing.

The last pedal on my board, which is a Korg tuner, really should not have been a necessity because the Venue DI has a built-in, onboard chromatic tuner. Sadly, it is not as responsive as other tuners I’ve used, and I lost confidence in its accuracy because of its oddball circular LED interface. Consequently, I added the KORG pedal and it works just fine! The raw guitar signal feeds directly into the Korg, which then cables into the Venue DI.

A handmade George L patch chord

It is worth noting that I use George L patch chords on both of my pedalboards. They are infinitely variable lengthwise because you build them yourself and have discretion as to how long the patch chord wire is. At my local shop, you purchase the plugs individually and the wire is paid for by the length. I keep a small coil of wire at home. The plugs are all nickel colored and the wire comes in multiple colors including black, blue, white and red. You build the patch chord by cutting the wire and then removing the cap to the plug. This is followed by inserting the wire into the opened plug and finally screwing the plug’s cap back down, which cuts the insulation on the wire and creates a proper circuit. I also use the optional rubber stress relief caps that keep the plug cap from unscrewing, which can happen over time. The George L’s are pricey. You can make 6 patch chords for roughly $100. My guitar shop guys consider them the best in the marketplace, but opinions around the web vary.

Genzler Acoustic Array Pro Amp

It goes without saying that an essential element in the signal chain is the amplifier itself. I currently use the Genzler Acoustic Array Pro amp and am very pleased with it. It offers a lovely transparent amplification of the guitar’s signal, which is a necessity when so much has been invested in the tonality of a Collings guitar. I would not want my guitars signal colored by the amp. The Genzler offers two channels, as well as chorus and reverb effects. I keep the effects turned off because I choose to use my pedals instead.

At home, I use one channel of the Genzler for the guitar and the other to practice singing my tunes. I own a very nice Sennheiser e965 condenser mic, which requires phantom power. Sadly, the Genzler’s phantom power is too wimpy to work with the e965, so I had to purchase a rechargeable phantom power booster that I stick between the mic and the amp and that works out adequately. I have not taken the Genzler out for a gig because I use a Bose L1 Pro PA; however, the Genzler is ready to go if I decide to use it. There is a socket built into the bottom of the amp so that it can be mounted on a stand at ear level for the audience.

The complete Acoustic Pedalboard

Above you can see the completed pedalboard. While there’s room for another pedal like the L.R. Baggs Align Chorus, I think this signal chain offers more than enough tone altering capability, without being excessive. You will note the pedals are velcro mounted on a Pedaltrain Classic JR chassis. Bolted below is a Pedaltrain Spark power block that offers 5 isolated power channels. Sadly, the Spark is no longer manufactured, but there are other power blocks in the marketplace. On my electric guitar pedalboard I use the excellent Walrus Audio Phoenix.

Below I offer some tone samples using various pedal combinations for both my Collings C10-35 and then my 0002H. I recorded the clips with an iPhone 11, equipped with a Shure MV88 mic plugged into its jack, and did final processing in Apple’s iMovie. The recordings are probably best appreciated with decent headphones.
