Two-Rock – Bloomfield Drive 100/50w or 40/20w Head, Silver Anodize, Slate Gray with Silver Cloth, Silver Skirt Knobs.

From TR’s website:

TR’s classic 2-channel platform, the Bloomfield Drive has new build techniques and upgraded components including their proprietary output transformer. When switching wattages on the 100/50w. transformer compensates for impedance and phase differences so there is no adverse affect on the tone or feel of the amp. The responsiveness, depth and bandwidth of the clean channel s instantly familiar, and cascades into an articulate, touch dynamic lead channel that is a pleasure to play. As an extension of the clean channel, this new lead channel gives the player rich harmonics, added gain, and a beautiful sustain. The highly effective tone shaping options include mini-toggle EQ switches for EQ1/EQ2, Bright, Mids, and Deep. Engaging the foot-switchable tone stack bypass to either channel pushes the amp to another dimension of overdriven tones. The Bloomfield Drive features a new sophisticated all tube spring reverb circuit specifically designed to not interfere with the overdrive channel so the reverb can be cranked and yet retain clear note definition, a sweet top end and touch sensitivity when pushing the lead gain. With the Send and Return control, you can tailor your reverb for any room or ambient effect you desire.
