Re: I want a lovely, warm British style amp
Heads Up - just remember, it gets extra help from diodes for that clipping sound.
Some do not mind that, some do.
That is true. But Hunter has been preaching for years to search with your ears. I just got done playing my HT-5, and the drive sounds great. But that's not the only amp I just got done playing...
Anyways, there's a lot of speculation about the preamp in the HT line, and I don't know how it works except in the 5-watter. In that amp, if the schematic I looked at was correct, the clipping starts in an op-amp passing through symmetrical diodes. From there, it goes through two gain stages of V1, then on along its merry way. The clean channel leaves out that drive IC.
The HT-20 and higher wattage models have an extra preamp tube. This gives you two more gain stages to work with. If I were designing the amp, I would use those to get a little more of that organic tube drive. I think I would leave the PI the way it is, and I would swap out the op-amp driving the diode clipping with a tube. Then, depending on how it sounded, I might get rid of the diodes and let the tube clip on its own.
But I've read internet speculation that the second tube is for the clean channel only. I don't buy it, because the original design shares the tube between the two channels. I don't think it's driving the effects loop, either. Before you say for certain that the Venue series has diode clipping, you may want to check your facts. I don't know if it does or not, but I'd be surprised if you really did know for a fact. And not because I don't respect your opinion. I just think if you knew it for certain, you would have given a lot more information.
And the bottom line is that it doesn't matter. The Blackstars are great amps, and they sound great. I think that's all you need to know.
By the way, Hunter, if you get to a dealer, sit down with an Artisan 30 for a minute or two. It's really impressive, even if it is much lower gain.
