The basis of all preamps, overdrives, and distortions is an amplifier stage on a jFET transistor, built in such a way that it simulates the behavior of a vacuum tube in a tube amplifier

The Alchemist Bass overdrive built on jFET transistors with low noise and good dynamics, thanks to the high (33 V) operating voltage.

The use of jFET transistors allowed to enrich the sound of the even harmonics. This makes it sound like a tube preamp and a good signal / noise ratio. All transistors are carefully selected by parameters.

This model uses a 4-band tone control:

Bass:     +- 20 db 80 Hz

Lo Mid: +-15 db 250 Hz
Hi Mid: +-15 db 750 Hz

Treble: +- 20 db 5 kHz

LPF:  Low Pass Filter for cutting "sand".

Blend knob mixes the clean input signal with the overdriven signal. The clean signal remains at unity gain while the volume of the overdriven signal is set by the Level knob, allowing for fine control of the blend ratio.

Passive true bypass.
Need external 9 VDC /
130 mA power supply  (not included).
