A combo amplifier with a 15’ special design Celestion speaker with a high frequency horn that uses a 12 band preamp and a 500W power stage. This combo has the same speaker configuration as the 1518c and the cabinet has been tuned, with an unobstructed bottom slot, to 42Hz, for great tight bass response.

Six footswitchable features that include:

Pre-shape for that classic Trace sound Valve to add valve warmth or overdrive 12 band classic Trace Elliot graphic equalizer Dual band compressor with separate controls for each hi and lo bands Sophisticated effects loop (hi-pass/lo-pass/full range outputs, left/right/mono returns, series/parallel switch, loop level control) Output mute (mutes all outputs except tuner out).

Other features included are electronically balanced XLR DI outputs for pre eq and post preamp left and right, left and right line outputs, MOSFET technology, and two valve/tube driver stages for signal pre-conditioning before the power stage. All the features listed above are provided in mono for the 1210 and 1215 combination amplifiers with stereo capability provided on the AH1000-12 head.
