Does this also apply to Fishman presys blend 301 system?

[@gilwe]

Interesting. I just got a fender on which the Presys doesn't work. I wonder if it has the very same issues.

Check Caps & switches

[@reginaldopazdefreitas2654]

Hi my friend. What are the specifications of the added capacitors? and which datasheet was damaged?

[@mikebchannel4329]

In my experience repairing fishman pks,almost all the SMD Caps are bad.You must have ESR meter to check these caps.If they are in low ESR or no ESR Value,replace them all.And don't forget to replace 2 switches for tuner & phase functiins.They all bad too.

Sir can you please tell me about the IC and the capacitors that used on that pickup bcs i have same issue with my fishman pickup

[@mikebchannel4329]

In Isys+, ICs are TL062&LF353 onswitch board and TL061 on cintrol board. Caps are six 10/16, one 2.2/16 and one 1/16. In Presys,eight 10/16 , three 2.2/16 and one 1/16.I forgot about the ICs...

Hello sir, I have (fishman presys plus). When I play guitar D string sound is coming very low, what’s the problem.

[@casadeiguitarservice]

I suggest to check the bridge saddle to be perfectly attached to the piezo, that should be the problem you have on D string

[@HiTadpole]

Where do you buy your ICs from? Thanks!

[@mikebchannel4329]

I don't buy.I search from old musical instruments audio boards.

[@jomsesguerra6140]

How about grounded unit?

[@mikebchannel4329]

I disconnected it.

[@junardmontederamos5124]
