DIY Mono Dual Buffer / Splitter Pedalboard Interface
The diagrams, templates, and materials listed correspond to this video (shown below), where I show all you DIYers
how to build a Pedalboard Buffer Interface system just like the pros! All of the info you'll need to design your own
customized buffer with options for mono, stereo, wet/dry, split mono, effects loops or 4 cable method, audition
loops, tuner outs, and more are all available as you scroll down the page.
The Mono Dual Buffer is ideal for any MONO pedalboard system running in front of an amplifier.
The Splitter Out provides a buffered feed for a second MONO amplifier. You can now use up to
two amplifiers that can provide a BIGGER mono sound and help fill in your tonal EQ and body.
*NOTE: Some multi-amp set-ups may require galvanic isolation and/or polarity reversal on one amp. We suggest the Lehle
P Split as a solution, placed as close to the amplifier as possible for the transformer isolation, and the polarity (phase) controls.
