We are now able to upgrade most fixed biased  models built from January 2011 onwards to the new AutoBiasMon, automatic biasing system . To understand this system and what it does please watch the video below.
​all Tucana 3 , SD60 and Triptik MK2 now feature this system as standard. For any models not listed, please send me an email: alan@carolannamps.com and I will figure out if the system is feasible or not for you.


​Please click here for detailed explanation of options and pricing:

The new Triptik 2 will feature a front panel switch and 3 color indicator for changing channels like whats fitted to this SD-60. Each press of the button loops through the channels. Once a foot controller or MI-01 midi converter is attached, the front panel switch is deactivated but the 3 color LED Indicator will still display the selected channel.  The amplifier above is a modified SD-60 'Stevie Dacanay' model with the front panel switch and the Auto biasing circuit that I did for the owner . He just happened to make the suggestion and I thought it would be a good idea to use it on the new Triptik 2 model.
