Trainer TS-15

Embodying solid-state preamp, delivers authentic, dynamic distortion


Only 2 left in stock. Grab yours until it sells.


Drunk Beaver Trainer is Traynor™️ TS-15 (solid-state amp) preamp section in a pedal format. I've used an exact schematic of the original amp with a very cool distortion texture. The preamp runs at +-15V using a standard 9V power supply (don't try to feed the pedal with a power supply higher than 9V; this will damage the electronics). The higher voltage gives you more dynamics and headroom (~30V amplitude, for example, Klon has ~27V). The preamp could be used before another amp or directly into the power amp section (for example, FX loop return input).


    • Gain - the level of drive.
    • Bass - controls the bass frequency response.
    • Treble - controls the treble frequency response.
    • Master - effect output level.
    • LED brightness trimmer - placed on the PCB trimmer allows you to adjust the status LED brightness.

    Power supply

    Power Supply: 9V DC adapter (Boss-style negative center) not included. No batteries. They are bad for the environment 🌲.

    Don't try to power the pedal with voltages higher than 9V - this will damage the electronics. The pedal uses a chip to run the circuit on +-15V.

    Voltage: 9V

    Current draw: 27.0 mA
