I have an RG2027. Played the stock pickups, played with the AN7/TZ7 combo, and now play with the AN7/Blaze Bridge combo.
The RG2027 IS mahogany, however, and I think that GREATLY changes things. That being said...
The stock Ibby pups were cool. Nice sound, not too hot, not too cold, not too much of anything. Versatile, slightly sterile, and were definitely middle-of-the-road, but in a basically positive sense.
The TZ7... good sound, and maybe would work GREAT for you. Not the best in mahogany, however, IMO. I did like the sound, but it was just too middy and round for my tastes. Almost too warm. Still, it's a fantastic pickup, and even with all that darkness (mahogany, TZ7, I tune to Gb!) I never had problems with mud/clarity. Always sounded clear and tight, just too round and midrangey (sounded perfect live and cranked, however).
Tried the
Blaze bridge, whoa! Love it. It's perfect for mahogany. That "thin" sound you mention, well, not in mahogany. The mid scoop helps the pickup to shine. Ends up sounding balanced, to me. Lots of bass, ultra-clarity, good treble and presence, and a very sweet, smooth upper midrange character, that is neither "warm" nor "clear" completely, but a great blend of both.
The AN7, sheeeet... 'nuff said. Best
neck pickup out there. Sounds fantastic.
So, I have the TZ7 installed in my basswood backup 7, but I haven't got the new electronics I ordered for it yet. I'm curious to see how it will sound. I should be getting them sometime this week/next week (backorder) and then I'll post if this thread is still around.
