Mad Professor Deep Blue Delay Pedal

SansAmp Bass Driver D.I. celebrates its thirtieth birthday! first introduced in 1994, it quickly became a permanent fixture in the arsenal of many bassists and studios. To mark its milestone birthday, Tech 21 is releasing a limited edition with an anodised, precision-manufactured billet aluminium housing and all-metal knobs. The fully analogue multifunctional pedal has been convincing for three decades with its wide range of applications, whether as a pure preamp or distortion pedal in front of the amp or as an all-in-one solution for direct routing to the live or recording mixing console. To this day, the SansAmp is the industry standard and ensures a good bass tone on countless stages every day. Happy Birthday!

What makes a good amplifier sound?Tube technology, selected high-voltage components, dynamics through high-voltage technology and an uncompromising analogue signal path.The BL 800 follows exactly this path. AVTC - Analogue Virtual Tube Circuit, selected high-voltage components, 280V operating voltage and a completely analogue signal path.The BL 800 is built like a real tube amplifier, with the same components, and that's exactly how it sounds!Sound without compromise:The BL 800 delivers a clearly defined, tight sound with plenty of attack. It also has a dynamic response and reaction to the guitar's potentiometer that only good tube amplifiers can achieve. The gain reserves surpass the good old JCM800, especially when the boost is switched on. Without the boost activated, the BL 800 is an exact sound copy of the JCM 800 with a little more gain; with the boost activated, there is a decent extra boost of gain.Controls:Gain, bass, middle, treble, volume, plus a gain boost. Five controls are enough to adapt the BL800 perfectly to an amplifier. This is achieved by an active 3-band tone control that covers all sound nuances. The boost adds a further scoop of gain without changing the actual sound of the BL 800.
