Our iconic Internal Pre Amp (IPA) in a box. Perfect for passive or active instruments, our External Pre Amp (EPA) is designed to seamlessly dovetail with your existing sound, while offering the exceptionally voiced 3 band EQ that our IPA preamp users have come to find indispensable. Get the Trickfish onboard preamp sound without modifying your passive bass or add a studio quality preamp/EQ stage to your pedalboard before or after your FX chain for added tonal control. Like the IPA, users can choose from two frequency points per band. This is done via dip switches on the back of the circuit board. Shelving bass boost/cut can be configured at 40Hz or 80Hz, mid boost/cut at 330Hz, 375Hz, 430Hz, or 500Hz and shelving treble boost/cut at 4kHz or 8kHz.

"I've been looking for a versatile amplifier that compliments the quality of my instruments and playing style. I love playing through my Trickfish rig! And as an added benefit, it's light‐weight and fits in the trunk of my car!"

"It’s everything I was looking for - warmth, balance, punch and power. The sensitivity or speed of the amp is amazing and the dynamic range is so musical… It was such a relief to just let go and play music without thinking about the amp. I love it!"

Jimmy Haslip
I have a Bullhead 1K and a TF112 and I have to say that this is the most musical rig I've ever owned. That head is incredible – I can get just about any sound I need and the cabinet is constructed like a tank. I'm in Havona as Jaco would say…"
