Tubes and Hybrids / what classifies as a SS reverb
October 22, 2015, 08:14:01 AM
Thought I would go to the source on this one.  No amp guru here...

Big heated discussion.  Specifics: Fender Hot Rod Deville. Was told (with serious snobbery lol)  its a solid state reverb because of the two tl072 op amps surrounding the reverb pan. Took a look at the schematic.. I liked it to more of a hybrid. from what I;m looking at.  Circuit (standard Fender stuff) simplified version ... it i.e. the signal looks to come from comes from a preamp ( a 12ax7 vac tube) into the tl072 then into the reverb pan, out again into the tl072..then if im looking at it correctly.... into another 12xa7 then moves to a 6LS (in Series?? ) hits the transformer then on to the speakers.

I don"t classify a ss as something that has vac tube in the IC (it also looks to me the the Tl072's are acting like values and nothing more)  again more of a hybrid. 

Honestly. I like what I see.  IMO.... The IC looks to prevent that nasty violent reverb slap back that one gets if playing the amp when/if it get's jolted (Which in my opinion can't be good for the amp overall)  And the Reverb quality is great and modern to the ear.   I'm wondering if Fender chose this method to prevent breakdowns. 

any comments? opinions?
