The Nova Delay iB Modified from TC Electronic is a limited run pedal with custom tweaks by famous tech Massimo Montovani. Massimo is the same man behind the sonic improvements of the G-System Limited. His modifications to the analog input buffer improves the TC Electronic Nova Delay's transparency, translating the right tone, feel and dynamics of your guitar signal to your amp. Value changes and higher quality components in the circuit dramatically improve the bass response of the Nova Delay iB Modified. Plus, all the great functionality of the original is there, including 6 delay types, tap tempo, modulation, spillover and reverse delay. http://proguitarshop.com/tc-electronic-ib-modified-nova-delay.html
