!!!TRADED!!!DOD Gunslinger mosfet distortion. Probably the strongest cutting bass dirt I've ever tried. $80 !!!TRADED!!!! !!!SOLD!!!DOD preamp 250. This one has updated switching and power jack, and added a nice bright blue LED to the front. The power input was swapped from the old 1/8" jack to a standard 2.1mm "Boss Style" input. Then, the circuit was brought back to the original "Grey" 250 specs, using a MC1458P dual op-amp, which is a dual 741, like the original had. Finally, the circuit was modified to have asymmetrical clipping, to more closely emulate how a real tube amp breaks up. Great low to medium gain tone. $80 Shipped !!!SOLD!!! Trade both for Tube Works Blue Tube 904 rack pre. Interested in other dirt pedals. Maxon hybrid Bassdriver, Tube Works Real/Blue tube....Nothing too over the top and articulation a big point of emphasis. I'm interested in the 2 extremes of dirt. Something that can do light OD and add harmonics and something for more saturated OD/distortion for the heavier tones.
