To avoid that kind of problems, we developed Bluetone Bias Rate bias adjustment system, which makes power tube biasing safe, fast and easy. Inside tube amp chassis there are dangerous voltages. In this case amp chassis has to be opened to to get tubes biased properly. Many tube amps have such a power tube biasing system, that it demands a skilled person to do it.

Many people avoid tube amps because power tube biasing is way too complicated.

More than just a simple two-knob design, the user has control over not just Reverb Type, Decay Time and Mix, but also Damping (which simulates the sonic affect of absorptive material, softening the high-frequency response), both a Lo and Hi Cut filter, and Dwell (which operates as a saturation control).Here we have gathered some information about tube amps and some modern technologies used in Bluetone amps. The update for BIAS Amp, BIAS Head and BIAS Rack includes nine different reverb types, covering a wide range of reverb colors and sounds. Reverb functionality has been one of our top-requested features worldwide, and we’re proud to deliver it for our customers with this free update.” Robert continues, “at Positive Grid we truly listen to our customers, and we make every attempt to improve our products based upon their comments and feedback. “When guitarists plug into our amps for the first time, they’re almost always surprised at how organic and authentic they feel – it’s like a whole new world of possibilities has opened up for them”. “The reaction to our BIAS Amp, Head and Rack products has been phenomenal”, said Robert McCullar, Vice-President of Sales. Known both for ground-breaking technological innovation and an organic and authentic feel, these products allow the user to experiment with different types of components in the virtual amp circuit – swapping tubes, transformers, tone stacks and more to create a custom amplifier designed specifically for the individual needs of each guitarist.
