Based on the vintage Fender tweed Bassman circuit. When these amps are set at low to medium volumes, you get a sparkling, harmonically rich tone. Turned up a bit more and it delivers that famous on-edge-of-breakup character that is responsive to your picking attack, a sound so craved by guitarists. Play a ringing open chord and you'll be rewarded with lush harmonic swirl. And then crank the volume up to 12 and you'll get a thick, creamy, meaty crunch - the original genesis for all heavy guitar sounds to come. And if you hit it really hard, you're rewarded with a slight compression, a slight sag in the response, that feels so good to play. The tweed Bassman is so touch-sensitive and responds beautifully across the frequency spectrum. With the Formula 5F6 you'll get that entire range of response! It does that quick compression on the initial attack that "exhales" quickly into a wide clean with lots of glassy chime on top and a tight full low end. Opening the bottom of the pedal gives you access to a switchable "secret lead" mode - a customized, high-gain voicing. There's also a Presence control to perfectly dial it in for your guitar rig. Runs on 9-18 volts.
