Ampeg Portaflex Experiences

Sign in to disble this ad
I'm on the hunt for a new "micro" system - lightweight is my main priority, but of course that won't be at the sacrifice of tone. I'm a long time SWR user (most recently a pre-Fender Redhead for the past 17 years), and always liked the sound I got from various pieces of their gear.

Today I went down and tried out an Ampeg PF350. The store did not have a PF500 available to try. However, they did have the 2x10 and the 1x15 cabinets, so I was able to test them each out. After reading reviews and the like on TB, I was looking forward to testing out this gear as their price point seems impressive, as does the sound quality people are reporting. I should note that I've recently been able to try out amps and cabs from Genz-Benz, Traynor, SWR, and TC Electronics. Prior to going into today's test, I've been really impressed with the GB and Traynor gear, and reasonably impressed (i.e. no major complaints, but no huge love) with the SWR (Headlite/Golight) and TC Electronic gear.

Cabinets first - I enjoyed the 2x10 Portaflex cab. Nice tight bottom end, and decent voice in the mids. The top end seemed edgy and harsh, but in retrospect I probably could have adjusted the tweeter level on the cabinet to get better control over that. Overall, for $399 and 40-ish lbs, this is a cabinet I could probably buy and be happy with, especially for for the price. The 1x15 Portaflex was a different story. No matter what I did, I couldn't coax a decent tone from this cabinet. Regardless of the settings on the amp or the bass (and I tried about 4 different basses with it), I couldn't get anything but a muddy tone that lacked definition. Regardless of price or weight, I wouldn't buy this cabinet. I'll add as a caveat I've played through 2x10 and 4x10 cabinets for the past 20+ years, so maybe 15s just aren't my thing.

Now the amp - I spent about an hour trying many basses (as mentioned above) with the head, but no matter what I did or what adjustments I tried, I couldn't get a sound that I liked out of it. The highs were either overly harsh or completely absent. The mid control seemed to do very little, whether I was cutting or boosting. The bottom end was lacking definition, although I suppose it could be described as warm when boosted signifcantly (i.e. past about 3 o'clock). However, whenever I would warm up the bottom end, the mids and highs would get slushy. Then when I boosted the mids and highs, the bottom end would drop off, and also there was no sweetness, especially with the highs - it was always harsh and edgy. As the reviews I read suggested, I tried to bring the gain up to a point of near-clipping in and effort to get a decent tone, but I can't say that I liked how it sounded as it was breaking up - there was nothing warm, tubey, or pleasant about it. If I had to use this amp, I'd definitely stay in the cleaner, lower gain ranges. On the positive side, there was lots of volume to be had, even with a single cabinet, and I did enjoy the aesthetics and overall look of the gear (especially the cabinets) as well as the practicality of the Portaflex system.

I wonder if the PF500 preamp is appreciably different than the PF350. I'm not someone who has used much compression in the past, so I don't know if that would make a difference or not, but perhaps the more adjustable midrange controls would help. Any suggestions or advice would be appreciated.

My conclusion from today's test was to go back to GB and SWR to find an amp that works for me, but to be open to the 2x10 Ampeg cabinet, especially for the price. As well priced, lightweight, and convenient as the PF350 is, I wouldn't get one, and unless the PF500 is dramatically different, it wouldn't be a fit for me either.

Of course, YMMV, and the whole review is IMHO.

Bass gear magazine - All the gear, all time.

In issue 4, you will find a review of the Micro VR that gives the setting they found that was as close to near flat sound as they could get was bass 10:30, mids 1:00, and treble at a lowly 10:00. The graph may not reflect "near-flat" sound, but it sounds pretty flat to me at those settings. The PF350 uses the same preamp, so yeah, they are definitely voiced to have a lot more treble boost than cut. I can find my favorite sounds with it no problem, and I'm not much of a fan of treble content. A little goes a very long way with me. But every amp isn't for everyone.

I don't know how the PF500 scopes out, but it does sound like it's voiced more up your alley. A little flatter when nooned, very much an Ampeg style voicing, plus you have greater control of your EQ. I'm sticking with the Micro VR, but if I were in the market, between the two PF heads, I'd take the PF500. But I'd take the SVT 7 Pro before any of them. Of course it's twice as much as the PF500, but it's seriously good...like a PF500 on roids.

Thanks for the input, it does sound like trying out the PF500 is worthwhile. I've had the chance to play through an SVT-4PRO on a few occasions, and while it is certainly not lightweight (unforunately), I did enjoy its tone and found myself able to dial up a nice sound relatively quickly...one of the reasons why I thought it was worth trying the Ampeg micros. Now I just need to find someone in town who has a PF500 in stock...

oops, small mistake...I wrote that the mids in Bass Gear's optimally flat setting was 1:00. Turns out it's just slightly past 12:00, maybe 12:15.
