The RECTOPLEXXX runs on whopping 24 volts internally (no extra power supply needed)
for maximum punch in every setting. The range of the DRIVE control goes from
a bone-dry crunch sound to tight, aggressive high gain sound for high-speed riffing.
SHAPE blends between mid-scooped metal sound and pronounced upper mids that cut through the mix like a machete.
Use the TREBLE control to tame the beast a bit or give the sound the extra edge.
Operation should be pretty straightforward, but just in case you can
download the manual here.
