Well, I finally packed up the RG88 in its wooden crate to return to Maven Peal. Dave Zimmerman had sent me one to evaluate and we all know what happened in the interim - whoever ends up owning this amp is in for treat, really. I've got to say that Dave Z. leaving the amp business is a great loss to us. One of the best amp designers in the World and truly innovatory. I hope that eventually he will return to the fold and make again Maven Peals in one form or another. This particular RG88 had been set up by Dave with two 6L6's and two 6v6's and in that form reminded me of old Twins or Pros. The two sets of power tubes can be set in any permutation with the two channels. Both channels are equipped with their own full set of tone controls ( Presence is shared) but also have a "Chime" control and a "Sag" control each. These two controls are vital in changing the overall responsiveness of each channel and the amp as a whole. Think of changing your amp from Blackface to Tweed and back again (and even more subtlly in between). I guess everyone has wanted a Chime control at some point or other - believe me this works (however, I wasn't comfortable at over 8.5 on the knob and you had to be careful with the Presence at high Chime levels). Channel 1 has a simple Volume control whilst Channel 2 (unusually for Maven Peal) has a Gain control and a Master. I used the Master more for balancing the level between the Channels. Personally I much preferred Channel 1 purely because I'm a low-gain freak and this Channel is so rich and responsive to the touch. As I said before one can go from Purr to Snarl just by the way you hit the strings. Channel 2 is probably the highest gain thing that Dave has produced. I like the way that you can play full chords at quite high gain levels without that "out of tuneness" that you sometimes get with other amps. Any high gain person would like this Channel I think, "power chords" are very crisp and raunchy with a deep but tight bottom end. No need for OD pedals with this amp. It shares one feature with all other Maven Peal amps (apart from the patented Sag control) that is you can set the tone and response that you like and then just alter the overall level with the "Watts" control - simply brilliant idea. Best, Pete.
