Mister CryBaby Super, Fender PT-10 tuner

[NickS]

Courtesy of Rob Prog, I've just received a Mister CryBaby Super:

and an unreliable Fender PT-10 tuner:

Wah first impressions: Same as Rob, I don't like the voicing of the Mister CryBaby Super as stock. I have an old (60s) CryBaby wah and it ain't the same, it doesn't do the talking thing so well. Time to go looking for schematics.

PT-10 first impressions: Not as much functionality as the Boss TU-2, but pretty usable and I may pass it on to my son until he can afford the Pitch Black he wants. Rob told me it was intermittent; I couldn't get anything out of it on Output 2, which is meant to be the output that's muted while tuning. Output 1 is connected direct to the input, with the tuner leeching off it. Not buffered, not true bypass; this is one solution:

The Output 2 jack is soldered to a small PCB. This PCB is soldered to the main PCB with a right-angled joint through a slot. That looks like a recipe for unreliability. I resoldered those connections and it's working for now, but I think I'll replace them with wires for future reliability. It also has an annoying faint background whine while tuning, which is exaggerated by any fuzz/boost pedal; I thnk this may be dependent on cable routing internally and is obviously for further investigation.

I could not open your hidden pictures, just the last one, did you add the switch to the on/off pedal or did older models of the TU-10 come that way? Mine has died on me and I'm having trouble figuring out what is wrong with it, so I'm thinking of modifying it to a A/B Box instead of a tuner. The power led is not coming on with 9V either from the battery or the charger. Is there a schematic somewhere to try to fix it? I suspect an over voltage spike might have damaged something, Thank you. Roy

A couple of years down the line the PT10 has come back to me; Matt has bought a Pitch Black because the PT10 was difficult to use in low light on stage, with just a red LED above the printed letter for each note. At least the # LED is green, not as per the stock pic above.

I guess I could change some of the LEDs for different colours to make that easier to work out...a little nose around Rapid Electronics may be in order.

Sorry to fenderjazz for not picking up his reply a couple of Christmasses back. The PT10 with a TBP switch through the pedal was something I found online, a bit drastic maybe but no doubt effective.

i've been using a pt10 as my only tuner for like 10 yrz. i hate the tu2's cause they don't start in chromatic mode.
