I see 2 TL702's on the schematic.
1 for the reverb send and recovery, and the other tied up with the preamp
send/return (effects loop).
| Quote: | input operational amplifiers in the TL07x series are designed as
low-noise versions of the TL08x series amplifiers with low input bias and
offset currents and fast slew rate. The low harmonic distortion and low noise
make the TL07x series ideally suited for high-fidelity and audio preamplifier
applications. Each amplifier features JFET inputs (for high input impedance)
coupled with bipolar output stages integrated on a single monolithic chip.

So, instead of using a tube for the reverb send & recovery, Fender used a
this op-amp instead. As far as the effects loop, same. I guess they decided
it would be cheaper to use ss components for those two tasks?
Why? if you don't mind me asking. |
