Silver anodized aluminum chassis with silver knobs, black bronco, black matrix grille cloth and white piping: the look Two-Rock gave the Studio Signature when it rebuilt the model.

The Studio Signature is Two-Rock's single-channel 35-watt amp, the current generation of the Studio Pro 35. It runs a pair of 6L6s through one channel built to stay clean and take pedals well, in a 1x12 combo that weighs 42 lbs. If you run your drive from the board and want a Two-Rock clean underneath it, this is the one built for that job.

The three-position Gain Structure switch on the back panel came over from the Classic Reverb Signature, and it sets how the input stage responds to your pickups. Up is the familiar Two-Rock feel and midrange. Down is a vintage blackface feel with scooped mids and a little less gain, cleaner and bouncier, and Two-Rock points humbucker players at it. The middle position has the most gain of the three and breaks up sooner.

Bright, Mid and Deep toggles sit beside a full Treble, Middle and Bass stack, with Gain, Master and Presence. The spring reverb is tube driven, with Reverb on the front panel and a Reverb Send on the back, so you set how hard the tank is driven as well as how much of it you hear. A low send gives a short, open, small-room decay; turned up, it gets saturated, with a sharper attack and a longer tail.

It has a passive effects loop and speaker outputs at 4, 8 and 16 ohms, and the speaker is a 12-65B made for Two-Rock by WGS.
