Bluetone Extreme Jr. is a very good choice for a guitarist who seeks world class guitar sounds with lower output power for home or studio work. This amp is based on legendary Trainwreck Express, which has been praised as one of the best guitar amps in the world. Anyhow this amp is not the best choice if player does not handle his instrument well enough.
Extreme Jr. contains some our own Bluetone modifications like 2x6AK6-power amp, PPIMV (Post Phase Inverter Master Volume) and VVR (Variable Voltage Control) to control amp output power and distortion. Because this amp is extremely dynamic, you can change guitar sound from shimmering cleans to roaring, distorted lead sounds only with guitar volume pot.
Power amp is based partly on Trainwreck Express and is partly own design. It has 2x6AK6-power tubes, which produce some 2-3 W output power. There is no need to bias power tubes when changing them.
Can you use spring reverb or effect loop in Extreme Jr.?
Many people ask if it is possible to have that kind of add on to Extreme. To make a long story short, it is technically possible, but to my mind both of them will spoil the legendary Express distortion sound and dynamics if these components are installed to signal path. Express distortion is mainly based on power amp and phase inverter distortion. They need a guitar based signal level of 10-30 V to start to distort. In an rack based guitar effect or spring reverb , the nominal operating level is some 1-2 V, which causes problems when integrated between preamp and poweramp. I have tested it in practise. It is highly recommended to use effect pedals which are connected between guitar and amp when it is a matter of Bluetone Extreme.
