We renewed our Bluetone AcDc Head by adding some new features to it like own ppimv master volumes for each channel and a built in Variac style OPC to get distorted “brown sounds” out of this amp. This amp is a true 2-channel tube amp, which is based on modified Marshall Plexi/JMP50 and Marshall JCM800/2204 worlds. It includes a footswitch for preamp channel switching. PPIMV master volumes will change automatically the same time when preamp channel is changed. This helps to get channels in balance when seeking power amp distortion.
Plexi channel has Normal and Bright input channels with individual Volume controls and a common tonestack (Treble, Middle, Bass). Input channels have an internal connection, thus no outside jumper cable is needed to use both channels parallel. Normal channel low register has been improved compared to original version and Bright channel has a little thicker sound than original plexi.
Crunch-channel has Gain, Treble, Middle, Bass and Master pots. This channel has also some Bluetone modifications in it.
Power amp accepts all normal octal power tubes like 6V6GT, EL34, 6L6GC etc. These tubes have to be rebiased when changing them. However this amp has an outside bias-point. With a Bluetone Bias Rate meter it is extremely easy to bias power tubes when changing them. Output power with a pair of EL34 tubes is 50-60 W. Amp also includes 2xPPIMV (Post Phase Inverter Master Volume), which allows to get all benefit of power stage distortion.
There is also a built in variac style OPC (Output Power Control) to enchanche power amp distortion possibilities. It also reduces output power, which is handy when playing in smaller places. Eddie Van Halen made Variac famous when using it in early Van Halen records.
This amp can also be equipped with a 2+2 power amp. Power tube pairs will change automatically when preamp channel is changed.
AcDc has also an integrated, buffered effect loop with an adjustable send level. It can be connected on and off with a remote footswitch. It can also be used as a Boost when there are no effects in the loop.
