MERMAN

TRANSPARENT OVERDRIVE

This pedal is discontinued. Please check our dealers or our Reverb store for any remaining stock.

Schematic created by BuggFX

The MERMAN VFE-ifies the original Klon overdrive circuit (and yes, we just used VFE as a verb). The original circuit uses three signal paths to achieve its unique, yet transparent tone. The MERMAN gives you control over the mix of these 3 pathways in the DRIVE, WARM, and BOTTOM controls. The COMP control fine tunes the compression in the drive section, giving you control over the precise amount of harmonics and dynamics of the germanium clipping diodes.

FEATURES & CONSTRUCTION

TrueSoft  Bypass

Variable HCC

Extended Headroom

DualMode Switching

We combine durable true bypass relay switching with an effect-side FET switch for pure and smooth switching.

Variable HCC circuitry allows you to fine tune the harmonics, compression, and clipping character of your tone.*

*Applies to COMP control only.

A charge pump is used on the tone and output stages for more headroom, and a fuller, more dynamic response.

DualMode Switching can convert the footswitch into momentary operation.

To use, wait 5 seconds, then press the sequence tap+tap+hold until LED flashes.

USA Made PCBs

Our circuit boards are made in the USA by Advanced Circuits (large PCB runs) or OSH Park (small PCB runs).

Noise Filtering

We used extra layers of noise filtering and shielding in the Merman to make this one quiet overdrive pedal.

HOW THE MERMAN CAME TO BE

THE STORY

"I can't count how many times I've been asked to build a pedal based on the Klon circuitry. I never want to do a new pedal design unless I can add some of my own original ideas. The Merman came as a result of many calculations to determine how to give the player more control, but without changing the fundamental tone and character that many players have come to love.

 

The Merman has that open, transparent drive tone we all expect from a great overdrive pedal. But now you can fine tune the EQ and compression response to better match your guitar, amp, and playing style."
