Wow! Fantastic amp! The speaker files are such an ingenious idea. Spectacular, flat, even response from my NV115s. They still have the unmistakable tone of 15s which I love, but the woofiness that’s typical of every 15″ speaker is gone. It sounds like an 18, 15, 12, 10 and 6 all at once! Unbelievable! The response is completely even top to bottom. And the eq is so responsive. Every little nuance that you add with the eq comes through. Best tone I’ve had in my 35+ years of playing bass! Thank you Jim. Very sincerely, thank you!!!
