buff Posted January 19, 2012 Share Posted January 19, 2012 Guess i spoke to soon, mine started cutting out on saturday nights gig after 4 numbers. Then the red peak light came on, but no fault or thresh lights. Had to turn gain and volume down under half, for it to start to not cut out. In desparation i plugged in my sansamp and turned up the level on the pedal to re gain some volume. Didnt have anymore issues. Tried it on monday same thing happened again. Now sent back to the shop i bought it from, who have as yet not found a fault with it. Quote Link to comment Share on other sites More sharing options...
Moos3h Posted January 19, 2012 Share Posted January 19, 2012 Same proble mine had. I'm beginning to wonder if there's a real problem with these! Quote Link to comment Share on other sites More sharing options...
buff Posted January 19, 2012 Share Posted January 19, 2012 Did you get your money back ? ive been offered an exchange on another amp so far. Quote Link to comment Share on other sites More sharing options...
Moos3h Posted January 19, 2012 Share Posted January 19, 2012 Yep, marked it as 'avoid' and have moved to GK heads now, touch wood, they've been fine! I think the PF500 has issues but there are those that have had no trouble! Quote Link to comment Share on other sites More sharing options...
buff Posted January 19, 2012 Share Posted January 19, 2012 It look's like theres a vast difference between outputs and reliability. its a shame, great sounding amp but no headroom or reliability. Unless you have a reliable one, which i thought i had until saturday night. Quote Link to comment Share on other sites More sharing options...
C88 Posted January 19, 2012 Share Posted January 19, 2012 This is a bummer, was seriously considering picking one up over the weekend, anyone know if the PF350 has similar issues? I was kind of hoping the problems discussed on TB were like 'first batch' sort of issues Quote Link to comment Share on other sites More sharing options...
grunge666 Posted January 19, 2012 Share Posted January 19, 2012 I'm in exactly the same position mate. I've got a Barefaced Super Twelve arriving tomorrow - replacing an SVT 410 HLF and now I feel the need to move on my 3pro. But, have no idea why!?!? I use a Sansamp RBI too so, I'm gonna go back to basics. Svt on its own 1st and only add the sansamp if I really need too. I like the idea of a PF500 though....

buff Posted January 19, 2012 Share Posted January 19, 2012 I had a pro for a while and never had an issues with it. Quote Link to comment Share on other sites More sharing options...
Lozz196 Posted January 19, 2012 Share Posted January 19, 2012 I`ve had my PF500 since about May last year, and not had any problems with it at all. I`ve read on Talkbass about some poor quality control issues on the early batches of these, but am surprised some are still coming through with problems.

Monckyman Posted January 20, 2012 Share Posted January 20, 2012 (edited) Still looking to change out my MB2 for a PF500,but was waiting for the dust to settle on these faults. Thought it had![quote name='buff' timestamp='1326998967' post='1505046'] In desparation i plugged in my sansamp and turned up the level on the pedal to re gain some volume. Didnt have anymore issues. [/quote] Now this to me suggests it`s the pre-amp stage that`s the problem,because using the pedal gain allowed you to pull the Ampegs gain pot right back and feed it a hotter signal to start with. I reckon less input gain and more master out is the way to go with these.Regardless of the compressor.

C88 Posted January 20, 2012 Share Posted January 20, 2012 Monckyman, if you don't mind me asking, how comes your looking to swap a LM2 for the PF500? I'm considering both at the moment and kind of saw the PF500 as a 'not as good, but could buy it new for the same money' sort of purchase.

Monckyman Posted January 20, 2012 Share Posted January 20, 2012 (edited) Hi C88. I love my Markbass, it`s utterly reliable,fits in my bag with a laptop, notes, cables and is a great platform for all sorts of pres and pedals etc. But.. I like Ampeg stuff, and was curious to see if the PF could match my larger pre and amp rig for tone and tubeyness etc. If it could, then I`d prob sell the heavy stuff on and save my vertebrae and suspension. If the PF350 had the compressor,EQ and headphones the same as the 500, I`d already own one as I don`t really need 500watts. As far as I can tell from reviews here and on Talkbass, the tone and power of the amp aren`t in doubt,and the musicality of the sound gets a lot of love here and the U.S, but the intermittent fault with cutting under load is worrying. The clues all seem to point to overloading the front end and causing a safety shutdown.But it`s not consistent across all the amps, a lot of people have no problem at all with it,so I`m thinking it may be accented by how you use the gain structure. Lozz seems to have avoided this totally I can recommend the Markbass as a lovely stable powerful platform, but if like me you want dirt or tube,and you`re mainly playing indie/alt/rock as opposed to jazz and funk I reckon you`ll need a pedal or two for that 3d harmonic thing.

buff Posted January 20, 2012 Share Posted January 20, 2012 Mine is now going back to the ampeg importers, as mansons couldnt find a problem with it. Quote Link to comment Share on other sites More sharing options...
