Unfortunately, no band currently so they are collecting dust
Is my situation too. The gigs are gone. What happened? It seems as if society has little use for local live music these days. My entire life's work has been made irrelevant by societies preference for turbo bass rap and free downloads. This would be an interesting subject for another topic, but not really relevant to fretless bass. My teaching practice is pretty much the extent of my musical life right now.
I too am an Ampeg enthusiast, they sound great. Ampeg amplifiers have a tone that to my ears, is the way bass is supposed to sound. My first amp was a 1960's Ampeg B15 Portaflex (Flip top) and my most recent amp is an Ampeg PortaBass PB800 with a PortaBass 212 (2x12) cab. In between I have tried just about everything and wasted a whole lot of money. All of my boutique amplification and speakers are gone now.
In order of frequency of use (and size):
- Ampeg PortaBass PB250 (PBC2112) combo w/1x12 neo.
Amgeg Portabass 212 2x12 neo cab. w/PortaBass PB800 on top.
Ampeg SVT 810e cab. w/ Ampeg SVT Pro 6 on top.
Ampeg SVT Pro 2 Premier Edition #076 all tube amp. Too heavy and for sale.
All made in the USA.
The Portabass line is discontinued so only available used.
The Ampeg PB250 1x12 combo amp is my favorite jazz, rehearsal, and all around useful rig. It sounds the best of all my rigs, but is too small for many situations.
The Ampeg PB800 is a great sounding amp and if I could only have one, this is the one I would keep. At 19 pounds it is not as light as the new micros's but this weight is no problem and it sounds excellent. Actually sounds better to my ear than the Eden WT-550 which has become my back-up amp. The Ampeg PB800 is one of those underrated and hard to find amps. It really is a keeper. Easy to tweak, easy to move, sounds good with just about any setting, and has enough power for 90% of the gigs I used to do.
UPDATE: 06/08/2014 - The Ampeg PortaBass PB800 proved to be unreliable. Too bad because it sounded great. Ampeg used a third party vendor to make a component called a Modulator circuit. These tend to fail and parts are not obtainable from Ampeg. Too bad. Back to the Eden WT-550 as my favorite mid size amp head.
The Ampeg PB212 cabinet also sounds very good and I recommend it if you can find one. Very light weight and has the sealed enclosure that I think has a tighter sound than ported enclosures. The only thing about the PortaBass cabinets is that their neo speakers cannot take abuse, so if you hammer your gear it probably is not the right rig.
UPDATE: 02/27/2013 - I have upgraded the drivers in the Ampeg PB212 cabinets to Eminence DeltaLite II 2512. The original drivers sounded fine but were lacking in power handling capability. With the new drivers it still sounds great and can be pushed a lot harder.
The SVT Pro 6 is another great amp. It is 2U rack spaces but very deep. Has tube preamp and a tube bias voltage control that is very cool. Parametric EQ that I like very much and 1130 watts of class A MosFet power. It is heavy but THE SOUND! Classic SVT sound (and more) without the reliability concerns and weight of an all tube amp.
Now, having said these good things about Ampeg products I should mention that they have exported their production facilities to Vietnam and are using wood products and parts produced in China. I have heard many reports about the inferior quality of the new products. I suggest that if it's an Ampeg amp you want, seek out a used unit made in the USA. I think that you will get a better bargain AND better quality.
One good note makes my day.
