The CORIBILT 16 started life as a 12 watt amp that I designed for Rob Tosh, a friend of mine who was tired of packing a Marshall Plexi and 4x12 cab around.
This amp was designed for simplicity and to be pedal friendly. No bells and whistles (Reverb, FX loop, Gain switching, Multi-class operation etc. These all rob tone and clutter up an otherwise simple, elegant design.) All components were selected carefully to provide a balanced response that would be warm and chimey with top end sparkle.
Over a period of four years we tweaked the amp until it reached its final form and wattage. I conservatively rate this amp as 16 watts but its closer to 18 watts.
As in all my amps, I used a ground plane layout, this is a labour intensive, but creates a very quiet amp with a very controllable response.
Allowing the use of various rectifier tubes enables the musician to select the compression and sag characteristics of the amp.
This amp is for the Blues and Rock player, it has enough power to play a large club, enough headroom to stay clean where you need it and low enough power to bring up the harmonics and crunch of a pushed output stage. This is a touch sensitive amp.
Although I tend not to do lines of amps, this is one of the ones that I get constant requests to build. I try to keep one around for demonstration but they tend to sell quickly.
