This particular amp is in great shape - only played a handful of times and has mainly lived in a studio.
The tone is gorgeous and the reverb is incredible. I don't really play much guitar anymore so I would like to see it go to a good home. Priced to sell because I could use the extra cash during the slow season.
$450, cash only.
More about this amp from VintageGuitar.com:
The Twintone is the Netherlands-based Koch Guitar Electronics company’s mid-sized guitar amp, a 1×12″ combo that, like the entire Koch line, uses top-quality components including cold-lacquered transformers, fiberglas-reinforced PC boards, and heavy duty potentiometers.
The Twintone’s all-tube circuit features a matched pair of Ruby EL34s housed in a punched-steel cage (to protect against breakage from loose footswitches or other items that may end up floating around in the back of the amp). The preamp section uses four 12AX7s protected with steel retainer strips. Its 11-ply birch plywood cabinet is covered in thick, black tolex and features cabinet-grade plywood bracing and back panels.
The Twintone’s 12″ speaker is a custom-designed ceramic-magnet Jensen VG12-90 rear-mounted on a presswood baffle. The brushed-aluminum control panel features large, black silkscreen with large knobs that complement the black/silver grillecloth and are easy to read on a dark stage. The overall quality look and vibe of the amp is traditional but still unique enough that you could pick it out of a crowd easily. Front panel controls include volume, bass, mid, and treble for the clean channel; and gain, volume, presence, bass, mid, and treble for the overdrive channel, as well as the power/standby switches and normal/bright clean-input jacks. The second input jack is voiced for guitars with humbucking pickups; it removes some mids and pads the signal slightly. The rear-panel controls consist of a channel switch for going from clean to overdrive channels (if you’re not using the footswitch), a reverb-level knob, series effects loop jacks, record out jack, headphone jack, and rhythm/solo level control. The rhythm/solo control can be pre-set and accessed via the two button footswitch, giving you, in essence, four presets – two for the clean channel and two for the overdrive channel.
