Great "bang for the buck" preamp for both live and studio use.
I ordered this pre-amp several years ago from this site and was blown away by the sound! I primarily use the unit for direct recording into some decent cabinet impulse responses, however I have used it live on several occasions with a power amp or slave head.
Cleans: Fantastic clean tone, sparkly, lots of high end, great character. Tone controls are incredibly effective here. Sounds great with a neck pickup for a bit of warmth.
Crunch: Classic crunch tones! Using the clean channel with the Hi Gain setting gets you some lovely breakup, especially when paired with some hot pickups!
Lead: TONNES of gain on tap here, though it does get a tad noisy when pushed to it's limits. It has a very distinctive high gain sound, not like a Marshall, not like a Mesa. Again, as with the clean channel, the tone controls are incredibly responsive and musical. It's worth noting that the high mid acts more like a treble control, and the treble more like a presence control. The contour button works brilliantly too, at enhancing the mid-range for a more cutting tone.
It connects effortlessly to other gear with line outputs with gain control on the back, and I've used it with a wide variety of equipment with no issues.
