Electro-Harmonix Pedal-Driven Modular Amplifier and Guitar Case Pedal Board w/ Milk Crate Speaker Enclosure

I had this old, plastic Pevely milk crate and a Celestion Vintage 10 sitting in my basement and thought they might pair up to form an excellent speaker enclosure for an amplifier.

There are quite a few guitar effect pedals in my collection and I had been actively trying to find some combination that would make a mean road rig, but had not been impressed with the results of my previous experiments.

I recently acquired an EHX 44 Magnum Guitar Power Amplifier pedal and wasn’t sure how it was going to sound, but the high wattage to low footprint ratio made it an attractive risk.

The 44 Magnum proved to be an excellent addition to my fully operational, Electro-Harmonix system, which is now comprised of the following components:

Electro-Harmonix Graphic Fuzz XO Fuzz Guitar Effects Pedal

Electro-Harmonix Germanium 4 Big Muff Pi Distortion / Overdrive Pedal

Electro-Harmonix Deluxe Memory Man Tap Tempo 550 Delay Guitar Effects Pedal

Electro-Harmonix Expression Pedal Real Time Variable Control Guitar Effects Pedal

Electro-Harmonix Oceans 11 Multifunction Digital Reverb Effects Pedal

Electro-Harmonix Analogizer Guitar Effects Pedal

Electro-Harmonix 44 Magnum Guitar Power Amplifier

Using these pedals, one can create the basic signal flow of an amplifier with slight modifications—entering at the Graphic Fuzz and then running to the Germanium Distortion, we start with an excellent tonal foundation and then add clean boost or overdrive/distortion. The Graphic Fuzz offers additional options for grit, but it also adds a fair amount of noise, so the fuzz is best left in the off position.

Next, we move into the Memory man for layering and the Oceans 11 reverb for a generous mix of effects. The Oceans 11 offers a subtle reverberation that plays off of Memory Man quite well.

In opposition to other preamps, the Analogizer works best from the rear of the signal, just before the power amp. It supplements any signal loss and allows fine adjustments to tone and depth, thus allowing the 44 Magnum power amp to amplify a balanced signal rather than compensating for power lost while traveling through the chain.

Speaker and Enclosure

The 10″ Celestion fit well in the bottom of the crate and a few brass nuts and bolts secured the speaker firmly.

Speaker Adapter Jack

I grabbed a spare speaker jack and a couple of components for making a 1/4″ jack. Using a 3/4″ steel spacer, a picture hanger and some electrical tape, I created a 1/4″ jack and then taped it to the top of the speaker jack.

A short length of speaker wire was used to connect the two jacks and then the connections were soldered. It’s simple, but effective.

I attached the adapter jack to the top of the crate using the remaining nuts and bolts and then wired the speaker to the adapter jack. Later, I added a 1/2″ plastic clamp to hold the 1/4″ plug in place.

Amplification

As mentioned earlier, the Electro-Harmonix 44 Magnum Guitar Power Amplifier will drive the speaker. This small amplifier supplies 44 watts of power, which is more than adequate for use with the 60 watt Celestion speaker.

Each of these pedals add small adjustments to the overall signal, which keeps the collective noise value lower than one pedal attempting to provide a similar level of adjustments alone.

Pedal Board Case

I looked around for a number of enclosures that would house all of these pedals in a workable package. Eventually, I ran across a small, seven dollar, electric guitar case that seemed to present an interesting solution.

It fits all of the core pedals and their power sources; plus, the expression pedal (that controls various features on the Memory Man pedal) can be stored away and separated from the main compartment.

Final Word

I’m not sure that this is the final incarnation of this pedal board, but at this point I am very happy with the performance of this present configuration.

Thanks,
