Pros: Small and light (1U), Sounds Great
Cons: A bit low on output power

This is a great preamp. Sounds great, looks great and is simple and easy to use. This preamp may not have a lot of features but it has everything you need. The sound is awesome, provides a nice thick low end growl and punch. The only problems I have are that it\'s a bit underpowered, if you want clean sounds you have to turn it down to a point where it\'s not properly feeding the poweramp, also the power switch is on the back so you have to reach around the back of your rack to power it up, but you get used to that. Overall this is a great preamp and I would higly recommend it.

Pros: Overall sound, light, reliable, DI
Cons: No DI level control for live playing

This is the only preamp where I could set everything flat, switch the bass boost on and plug any bass into it and love the sound. Any other preamp I've had required some EQ and volume adjustments to be useable.

I wish there was a 1K EQ band but other than that, it's darn near perfect. I haven't experienced any unwanted distortion and have been able to get a lot of clean volume out of it. If you turn the gain all the way up it will overdrive the tubes which is kinda nice. Not the best overdrive I've heard but still pretty useable. It's got the famous Jensen DI which soundguys love for running the PA and recording. The only negative thing is there's no output level, which would make it much more useful.

They sold new for a decent amount of change but are going for $500-$600 used. Still more expensive than a lot of other preamps but it's worth it. If you're looking for punch and warmth and a good overall tone, it's in this preamp.

Edit: I just recorded with this pre for the first time and it's absolutely amazing!!!! Everything was set flat and switched to "pre-EQ" on the output and gave me the juiciest, thickest tone I've ever been able to get. I didn't have any issues where a DI output level control was needed, although for live playing I think it might still be a necessity.
