Three Knob
This is our flagship design. Gain, Tone, and Master Volume controls are all you need to dial in this rock ‘n’ roll monster. The amp features a straightforward, all tube signal path, Mercury Magnetics transformers, carbon comp resistors, point to point wiring and selectable 4/8/16 ohm output impedance. This is a classic rock amp with responsive crunch and also a great platform for effects pedals…
One Knob
Yes, it only has one knob. The One Knob amplifier has the same specs and options as the Three Knob, but has no Tone or Master Volume controls.
Dual Three Knob
This is a two channel version of the Three Knob amplifier. It has two identical and independent Three Knob channels that are foot switch selectable.
Magpie Custom
Looking for something cleaner with more bite? The Magpie Custom is inspired by classic Hi-Watt style designs and built with Big Crunch quality. The original build was a special request by J Robbins and has been featured on many Magpie Cage recording studio sessions. The amp was also seen on stage for the most recent Jawbox reunion…
Big Crunch Bass Amp
ALL TUBE
This is a hand-built powerhouse. We worked hard to design the most stable all tube output section we could. It runs 4 KT88 power tubes, uses Mercury Magnetics transformers, has three band EQ, selectable 2/4/8 ohm output impedance and a balanced XLR line out. The model pictured has our Big Crunch overdrive pedal integrated into the amp!
