Howdy,
Just purchased my PF-500 today at 2:30pm for a gig at 4 - I play an Explorer bass in a pretty loud punk rock band so the volumes are pretty challenging...
I also play in a myriad of other groups and have always loved Ampegs, around the horn. But this was a test run to see if this amp would be up to the challenge of this particular group.
My sound is a LOT of gain - not fuzz bass really - but crunchy, growly and kind of harsh, and I play hard. I was pysched to try this amp out, and super pysched about the mobility factor of this tiny thing.
Anyhow on the gig in the MIDDLE of the FIRST song the amp went dead with the 'fault' l.e.d. lit - it was overheated I guess. After 1 1/2 minutes?!?! It was a hot room sure, but nothing extreme - the gain was at about 1 o'clock; the master on about 3. LAME.
I shut it down, the band played through the rest of the tune, then brought the gain and master down. It came back on, then in 30 seconds, same thing. REALLY LAME. I borrowed the 1st band's Peavy combo 300 and killed it the rest of the set. Say what you will about Peavy, the things are tanks.
I'm returning the PF500 first thing tommorow, and Ampeg should give vouchers for the money spent driving to get this lame box. I can't imagine how this amp would work for anyone with any kind of moderate volume in their band.
It really pains me to read of someone having a bad experience with a piece of kit that I just happened to have purchased, especially when my experience has been the polar opposite... I've been on both sides of this, so I feel your pain hipcat...
Was asked to jam today so I had the perfect opportunity to test the PF500 two days in a row... Yesterday with a minimally amplified 'acousticky' group, and today with a loud blues-rock group...
Brought a bit of gear, as I wanted to do some 'comparison' testing... The PF500, my '71 Ampeg V4, a 3015 equipped TL606 cab, and my V4 cab running 2 2512s... Basses were my '96 MIA P bass and a '95 RI Dano Longhorn... Also brought my Musicmaster bass amp for the guitarist to try (he's thinking of getting one)...
First off, this is a LOUD group of guys! The drummer pounds and there was an extra guitarist that I was unprepared for... I started off with the V4 head into the V4 cab, a totally winning combination and loud as balls! One thing about this setup: Killer tone is effortless! Played that for a few songs and took a quick 'beer break', during which I hooked up the PF500 into the V4 cab...
With the PF500, I immediately noticed an increase in headroom as well as a removal of 'grit' in my tone... More clean headroom than the V4 (which is not known for clean headroom, but in a good way!)... I cranked the gain a bit which added some 'fur', but decided I liked the tone better clean... Ran the compressor at 10:00, gain at about 11:00 and the master at 1:00 and was sitting nicely... Bass at 1:00, mid switch set to 3 with the control at 2:00, treble at 12:00 yielded a great tone with the P, and I kept it there until the next 'beer break'...
Next up, hooked the PF500 up to the TL606 as a stand-alone... Since it is an 8 ohm, single driver cab, (the V4 is 2X12wired to 4 ohms), I noticed a volume drop... Left everything where it was and boosted the gain to 1:00 and was right back in the game. This head with this cab is an awesome combo! After a few songs (and another beer!) I switched to the Dano (my Dano's are rapidly becoming my go-to gigging basses)... It runs quieter than the P, so I goosed the master to 2:00 and left everything else where it was... Very happy with the tone... Engaged the low switch and, like others, noticed that this scoops the mids somewhat... Switched the mid selector to position 4 and was cutting through nicely while keeping a fat bottom... Stayed there for the rest of the day... Never felt at a loss for volume or headroom...
Today was a nice validation for me and a bit of a relief... 4 hours of rather loud playing (for me anyway... Certainly louder than my main gig!) without a hiccup gives me some confidence... It also has convinced me that my cabs kick some butt! I'll be going into next week's gigs with a clearer sense of what this rig can do ITRW and feeling pretty good so far about my choice
