Features

Dial In Warmth Without Losing the Bottom
Set Drive for grit, then use Blend to bring back your clean signal. Around 10 o'clock on Blend gives a warm, chewy tone with the full low end still there. Shape it with Bass, Mid and Treble.

Send a Quiet, Balanced Feed to the Board
Plug any standard XLR cable into the output. If you hear hum, flip GND LIFT. Flip CAB SIM for a mic'd-cabinet sound. Both toggles are recessed so they stay where you set them.

Split Your Signal Two Ways
The XLR carries your shaped tone to FOH or your interface. The parallel 1/4-inch thru sends a clean, dry copy to your tuner, stage amp or monitor wedge.
CNC Aluminum, Not Plastic
A 6061 aluminum chassis with 2.2mm walls, metal-nut jacks, a locking XLR and recessed toggles. It weighs 410 grams and feels solid under a boot.
Two Outputs, One Pedal
Send your shaped tone to the board over XLR and a clean dry signal to your amp or tuner from the parallel thru, at the same time.
Balanced XLR + Ground Lift
A 600 Ohm gold-plated XLR with phantom power protection and a -98dBu noise floor. One flip of GND LIFT kills ground-loop hum.
Analog 4x10 Cab Sim
Switch it on and the direct feed sounds like a mic'd 4x10 cabinet, with the harsh clank above roughly 4.5kHz rolled off before it hits the PA horns.
Active 3-Band EQ
+/-12dB at 80Hz for weight, 500Hz for punch and 3.2kHz for attack. A small mid boost gets you through two loud guitarists.

Questions
Does turning on the drive kill my low end?
No. The Blend knob mixes your untouched clean signal with the JFET drive, so the fundamental stays in. We confirmed it with a low B (30.87Hz) on a spectrum analyzer.
Do the EQ and cab sim affect the parallel thru jack?
No. The EQ, drive and cab sim shape the processed signal on the XLR. The parallel 1/4-inch thru sends a clean, dry copy to your tuner or stage amp.
Does the cab sim work on the XLR output?
Yes. Flip the CAB SIM toggle and the XLR feed gets an analog 4x10-style voicing that rolls off harsh string clank above roughly 4.5kHz.
Will the footswitch pop through the PA?
No. The switching is pop-free. We stepped on it repeatedly through a full PA at performance volume and heard no thump.
Can it handle an active 18V bass?
Yes. The 1M Ohm input has enough headroom for vintage passive pickups and hot active preamps. Our active 5-string didn't clip, even on the low B.
