This Two-Rock Bloomfield Drive 40/20 Watt Head is in the standard Bloomfield Drive Cosmetics (Slate Gray, with Silver Grille, and Blue Piping), with Silver Chassis, and Silver Skirted Knobs.
Why We Love It: While the 100-watt 6L6 variant gets plenty of spotlight, this 40/20-watt quad-6V6 head is the true sleeper choice for the working musician. It delivers the legendary, uncompromised touch sensitivity and three-dimensional depth of classic Two-Rock cleans, but cascades into a sweeter, warmer, and more dynamically compressed overdrive character that you can actually push to the sweet spot at sensible stage and studio volumes.
- Best For: Session Work, Studio Work, Worship Stages, Blues, Fusion, Small-to-Mid Venues
- Tone Profile: Warm, bloom-forward, articulate midrange with a round, singing sustain and a completely non-brittle top-end chime.
- Compared To: Breaks up earlier and with smoother, rounder compression than the 50W or 100W 6L6 variants, providing rich power-amp saturation at significantly more manageable decibel levels.
Expert Note & Overview:
The Two-Rock Bloomfield Drive redefines the dual-channel cascading gain platform. At its core is a proprietary output transformer that automatically scales the power section from 40 watts down to 20 watts without causing an impedance mismatch or sacrificing an ounce of tonal bandwidth or playing feel. The highly interactive tone stack includes mini-toggles for Bright, Mid, and Deep boosts, as well as an EQ1/EQ2 voicing switch to shift between tighter vintage or broader modern response profiles. Need more push? The included foot-switchable Tone Stack Bypass completely unfurls the preamp layout, transforming either channel into a raw, harmonically explosive overdrive beast. Finally, the all-tube analog spring reverb features dedicated front-panel Send and Return controls, allowing you to perfectly sculpt a lush, ambient space without masking your fast right-hand articulation or clouding up high-gain lines.
This head features Two-Rock's sleek standard aesthetic package: gorgeous Slate Gray Tolex bound with blue accent piping, a pristine silver thread grille cloth, a Silver Anodized Chassis, and classic Silver Skirted Knobs.
