Thanks Thor ,
I had noticed some smaller switcher powered tube amps doing the rounds ,
Many of the Vox amps are class A ,so HT current doesnt vary very much ,
In Class A/B amps the HT current varies appreciably from zero to full signal , I cant imagine an SMPS doing anything good for the tone during heavy clipping , Sure some mains noise moduated into the sound with traditional style PSU's , but thats a devil we know well .
Ive noticed in the age where modern stomp box type effects pedals come with small SMPS wall warts many problems with multiple SMPS interacting and causing horrendous noise/ mush all over the signal .
Fancy DSP stomp boxes which use amps of current are the usual suspects in this regard , garbage is mixing and combing via multiple paths and what comes out sounds little better than an Edison wax cylinder recording as far as signal/noise and distortion levels are concerned .
I know one very tallented guitarist whos put up this ******** for years , I did take a look at his set up at one point and offer my advice to him ,
But hes a hard head and in the end my time was wasted , he stuck with his 35db S/N ratio .
I think he plays more acoustic these days so crowd noise defines the S/N
One time on a recording session with a few friends the Bass player had got the latest and greatest SMPS/Class D/ amp head , weighed only a few kg .
It had a DI out which I decided to try into the line in on the Yamaha HDR/mixer so we could use the amp eq compression etc to tape ..
The Genz-Benz threw a rod when I hooked up, all the virtual knobs bells and whistles were out to lunch , sound gone.....
There was a moment when the owner thought I'd killed the F'cking thing
He was having a major malfunction and was about go into meltdown until I flipped the power off and on again on the Genz Binz.
Lucky really because he's a big lad .
A standard active DI box and we were back in the groove again and all the fuss was forgotten .
A really memorable session , I must dig it out and cut the whinging whining and argueing between the takes .
