Developed after months of forensic examination of vintage valve amps, the St. James series offers valve amplifiers that are truly lightweight and portable.
Available in a classic EL34 design, these amps are simple to use but highly versatile; the intuitive two channel set-up deliver Blackstar's best ever cleans and overdrives.
The EL34 models use a 'classic' valve/tube preamp topology for Channel II which is based on a much loved British 'class A' amplifier of the early '60s (Vox AC-30 Top Boost). This is a low to medium gain preamp that can be used clean, warm or mildly overdriven. Again, this is a very popular choice for a 'pedal platform' as well as for a great responsive crunch tone. When this channel is selected the valve/tube power stage is set as 'open-loop'. This has a looser feel with a resonant bottom end and lively highs.
The footswitchable BOOST setting pushes the valve preamp harder with a +10dB clean boost, to take it from 'chimey' to 'creamy' and beyond.
All models feature a 3-way 'POWER' switch to give the user options on how their valve/tube output stage is run.
