Greer Amps SOMA 63 Vintage Preamp Pedal

Dial in vintage tones from the brown era of California amplifiers! Greer Amps' SOMA preamp/distortion pedal gives you the tone, grit, and feel of a '63 amp.

A brave new world of tone, the SOMA '63 Vintage Preamp is the first pedal in the XFR series of pedals from Greer Amps. The SOMA '63 is a true vintage preamp, based on the tone and feel of vintage brown era amplifiers from California. This pedal simulates the entire preamp, phase inverter, power section, and even the feel of the vintage 10 inch Utah speakers that were in those famous brown amps.

The tone stack is designed to provide a wide and dynamic range of tonal options to the user. The Presence control works with the tone stack, and is designed to be a wide range control, effecting the overall sound of the entire circuit. The SOMA '63 features a steel core transformer in the audio signal path. The transformer lends to the overall tone shaping of the circuit, and when the gain is pushed hard, especially with higher output pickups, the small steel core transformer will saturate, just like a vintage amplifier. The SOMA '63 can be used as a tone-shaping preamp, or as an overdrive pedal. There are a wide variety of tones available in the SOMA '63, so spend some time with your pedal, and find the tones that rock your world!

The SOMA '63 runs off of a standard, negative center pin 9 volt power supply, and can be ran off of up to 18 volts. At 9 volts, the SOMA '63 will have more grit and texture. At 18 volts, you can expect higher headroom, a bit stiffer response, and less overall grit.

I have had many dirt pedals to analogman to Death By Audio, Origin Effects, EQD Boss and other brands and this hands down the best dirt pedal I have ever had.I have play offset guitars in to a Fender Twin and it is a match made in heaven.Its stacks beautifully with just about any pedal especially with a Lightspeed and it makes all of delays and reverbs sounds better. Hats off to Nick Greer
