Roadhouse USA:
Carvin Quad-X 4-Channel Vintage Tube Rack Mount Preamp.
These were an excellent sounding tube preamp made by Carvin.
A very wide array of tones are possible with this little 2-rack space preamp.
Excellent working condition, just a little wear from being racked and thats about it.
4-channel tube preamp (9 12ax7):
Channel 1: Clean (1 preamp stage, 1st stage of tube 1), volume, low, mid, high
Channel 2: Clean (1 preamp stage, 2nd stage of tube 1), volume, and low, high EQ, cloak shared with channel 3
Channel 3: Clean (5 preamp stages, tubes 2, 3 and 1st stage of tube 4), volume, crunch and low, high EQ, cloak shared with channel 2
Channel 4: called Sustain (and rightly so) (11 preamp stages, 2nd stage of tube 4, and tubes 5, 6, 7, 8, 9), volume, gain, low, mid, high
Boost switch, bright, separate EQ for the master.
Effects loop on the master and specific loops for each channel.
True reverb that simply sounds.
Good quality noise gate circuit.
Ultra-comprehensive connection options (jack, xlr, stereo, mono outputs with separate volume controls), inputs on the front and rear, footswitch jack for each channel (on the non-MIDI version).
