JP6 electronics problems - an extremely happy (UK) chappy now!!
Hi there,
A few days ago I took delivery of a gorgeous JP6, fully loaded minus the inlays, I paid a fair price for the instrument believing it to be in good working order, which largely it is except for one problem which is driving me completely nuts.
When a mono signal is derived from the 'mix' socket, on rare occasions the sound can be distorted, weak and buzzy, this is true of the signal from all pickups, the magnetic and the piezo, swapping the jack plug to the 'magnetic' output produces a perfectly clean signal, the magnetic output is therefore not affected by this fault.
Being the owner of a Taylor and an old Takamine electro-acoustic, I identified the distortion as being very similar to the sound produced when a battery is dying in those aforementioned guitars.
I won't bore you with all the checks I made, suffice it to say, the batteries are good, there appears to be no suspect solder joints on the jack socket pcb, I've cleaned the battery housing contacs with isopropyl and yet every now and then this distortion occurs making me want scream in frustration.
Whilst the distortion is happening, tapping the battery housing makes no difference to the problem but what I have found is this. If the battery is removed and then re-inserted the signal returns to normal, that's it, that's the cure, take the battery out and put it back in, weird. Like I said, I've cleaned the contacts in the battery cradle so what in God's name is going on here, any ideas at all?
In all respects the JP6 is pretty much my dream guitar but if I can't sort this one out, that dream could rapidly turn into a nightmare. This is a three year old instrument which has never been gigged, it is near as damn it as new!
I throw myself upon your mercy.
