Last night Miko Espanol & I did this shoot out. Cabs were an original EA NL120 and Berg HT112 ER stack. Basses were: Fodera Beez Elite (passive w/ Aero's, Ash / Ebony / maple) Nordstrand NJ Active/passive w/ Big Singles, Alder / Cocobolo / maple. The amps were all set pretty much flat w maybe a schosh of bass. First came the 502. Predictable basic great tone and power. I love that amp. It felt the most powerful of the bunch. It was like a monster compared to the rest of the uber lightwieght field, but we both liked it a lot. Then onto the Shuttle. Very clear, thumpy, and in your face, sounded best with the BERGS , but for both of us our least fav. (We both are pretty much fingerstyle players) Form this point, we pretty much went back and forth between the 502 and the PUMA. Enter the Puma 500. Just lovely, much like the 502, but a bit "creamier" I found it very musical. Elegantly simple. The real suprise was when we mated it to the NL210. WOW. It sure likes that cab, IMO, that was unlike any of the other combo's. For me that was it. Fingerstyle heaven and PUNCHY, growly , never harsh. I think 2 NL210's would be over the rainbow. I was going to sell that cab till i heard the PUMA with it. I liked the PUMA 500 much more than the 1000. TECAMP only had the 1000 at NAMM and i thought is was rather blah, no big yank.
