We’ve made some slight changes to Vandal’s bass amplifier recently.
It’s still an all-tube design, coming with 3 tube gain stages in the preamp section and delivering a fat tone through the push/pull pentode power amp stage.
Here’s the new pot layout:
So, we’ve changed the preamp a bit: Now, the signal first enters the first gain stage, then can be shaped via the ‘contour’ knob (kind of loudness / lower mid dip; an interactive / passive filter network), then gets some compression.
The compressor is a FET-based feed-back model, similar to some stomp designs or vintage studio rack gear. It’s ultra-transparent and musical; you can kick it hard and it still doesn’t do strange things.
The ‘drive’ control feeds an extra tube stage for extra harmonics and extra oomph 🙂
The EQ section is a split design: a passive low/high baxandall network followed by an active 2-band mid control. All filter slopes are 6dB/oct, which in our opinion is the best compromise between being versatile and retaining the character of your bass guitar.
Here are some audio clips:
basstest_dry (VANDAL completely disabled. A bit of silly & aimlessly fingered playing)
basstest_vandal (the amp setting from the picture above)
basstest_vandal_chorus (VANDAL’s stomp guitar chorus in front of the amp)
Here’s a clip by Dimi, certainly in a more sensible context: 😉
