So does it mean the bassman 100 gets distortion very fast?
When I am playing in a bar (e.g 200 people)does the bassman 100 gets a distortion because of less power.
Is it a cool distortion?
I loved ampeg CL + 810 all the way, but i sold it because it was too big for me.
I dont play that big shows anymore.
So now I have only a reddi (SVT sound) and looking for a different bassamp. Like bassman, orange or maybe hiwatt 100....
Relative to the 135, the 100 does move into distortion sooner because of less power. The transformer in the 100 is like what you find in most amps. The additional taps found in the ultra-linear Fender amps are similar to what is used in many hi-fi amps. The design keeps the power amp cleaner. They do still distort when cranked, you can get more clean headroom out of them. The 135W is a higher power amp, it will be louder than the 100W amp. Guitar players love the distortion of the blackface amps. But the 100 can be played clean. The more speakers in your cab, the louder it will be. So the speaker cabinet that you use is important.
The problem with buying any vintage amp is that you don't know if it is performing up to spec. If the power supply capacitors are old, the amp will distort sooner. If the tubes are weak, there will be issues. The same goes for resistors and capacitors in the amp. There's a lot of work that a vintage amp may need. This can be costly. Of course you can find vintage amps that have been well maintained and don't need any work. If at all possible, find a 135 and a 100 to audition and see which one will best meet your needs. I know that this isn't always possible.
People buy vintage amps for different reasons. Some because they had one in the past, others because they want the look or the sound that they offer. People buy these amps knowing that they will need to put a lot into them to restore them to spec. You want an amp that will performer as well as it did when it was new. Often the restoration is a labor of love.
If you are on a budget and want to get the most out of your purchase, seriously consider a new amp. The advantage is that you have a warranty and you'll have many years of service. A lot of people like the Ampeg V4B reissue, the Orange AD200B MK3, as well as the current Fender amps.
I had a 135 Twin Reverb that I bought new in the 70's. It was the one amp that I wished that I never sold. It was a combo and was pretty heavy.
