Spark Positive Grid 40 Queries ....
-
Hi All,
Just purchased a second hand Spark 40 and struggling a bit with it. I've factory reset it to default.
Was testing out the four "presets" and they all seem to have a fair bit of hiss when you use them, especially preset 4. Not blown away.
Even on the clean setting you can just detect a faint hiss as you play.
I tried using headphone, but the hiss persists so not a speaker issue.
The hiss is only obvious as you play, it's not constant.
Have I picked up a dud one ....

Cheers!

@john-davis-flann You may have been sold a dud.
If you look around the forum, the latest firmware update has bricked tens of thousands of Spark amps- the original, and now the mini.
About a month ago, after applying the firmware update, I started getting a hiss, but now I get ZERO sound.
Have you tried applying the latest update? If you're lucky, this may be your fix, or it may brick your amp. If you bought the amp from ebay, I strongly suggest you return it.
I've been going in circles with PG tech support via email for 2 weeks, and they're a nightmare. I'm here to see if anyone has tried something I haven't, to get sound back. Just giving you a heads up. Good luck.

Hi Wu Tang,
Thanks for the reply. It's a bit of a disappointment to find out there are such problems with a high end and expensive amp. I bought mine second hand locally and have no recourse to return it. Unfortunately I did not check out ALL the presets when I was test driving it.

Do you know if there is any way to downgrade to an earlier firmware?
Cheers,
John.
