Alchemist User Manual How to use it: Read this owners’ manual completely before use to fully understand your Alchemist’s functions. TREBLE GAIN MIDDLE BASS VOLUME GAIN TREBLE INPUT BOOST CLEAN CRUNCH BRIGHT DEEP PUNCH CHANNEL Channels/Boost The channel on the left is the Gold channel. The channel on the right is the Mercury channel. Each channel has its own character and set of tone controls. The boost, delay, reverb and effects loop apply to both channels.
Alchemist User Manual GAIN TREBLE MIDDLE BASS VOLUME DELAY REPEATS REVERB STANDBY 40 W ON PUNCH BRIGHT MID SHIFT 20 W OFF PLATE HALL SPRING DUCKING TAPE ANALOG TAP Delay The built-in delay effects apply to both channels, and give you a choice of 3 personality-rich effects. • DUCKING – This is a digital delay. The mix level automatically responds to your playing volume, reducing the level of the delay while you are playing, and increasing the level when you stop playing.
Alchemist User Manual Reverb The built-in reverb effects feature studio grade digital processing. The 3-position switch chooses between: • PLATE – Emulates a classic studio plate reverb. • HALL –The sound of a large space. • SPRING – Classic spring reverb sound. Whichever reverb you choose: • REVERB – This knob sets the level of the reverb effect. The reverb signal is applied in parallel to your dry signal, so your dry signal never goes through the internal effect unit.
Alchemist User Manual FX Loop For the best tone, set the mix control to 100%, on the effects that you place in this loop. This is a non bypass-able buffered parallel effects loop between the pre-amp and power amp circuitry, parallel to the internal effects. The dry signal never leaves the amp, ensuring the best tone. This loop is designed to work with instrument level pedals. Line level effect units with level controls should work just fine as well. • SEND - Connects to your effect units’ input.
Alchemist User Manual Tubes Your Alchemist comes with a matched pair of 6L6 power amp tubes depending on availability. Five 12AX7/ECC83 tubes are used in the pre amp. See below for individual functions. Note: If you want to experiment with different tubes, you can reduce the potential for amp noise by 1) choosing lower gain tubes, and 2) placing any higher gain tubes earlier in the signal chain (the signall flows in order from V1, to V2, etc.).
Alchemist User Manual Changing Tubes Make sure you turn your amp off when you switch tubes and be careful, the tubes might be very hot!! Do not touch tube sockets with fingers! Even after turning your amp off and unplugging it from the power outlet there could be enough voltage stored in the capacitors to give you a lethal electrical shock. Most amp problems (microphonic squeals, crackling, low power, mushy bass response etc.) can be traced to bad or weak tubes.
Alchemist User Manual Fuses To check the fuses, use an Ohmmeter to make sure they’re blown because sometimes you can’t see if they are. Radio Shack is one source that carries both types of fuses. • MAINS FUSE – This is a 5x20mm Slow Blow type. 100-120 volt operation requires a 2.5A fuse. 220-240 volt operation requires a 1.25A fuse. If this fuse blows it could be just a voltage peak from your power outlet. Put a new one in and see what happens. If it blows again give us a call.
