Pro Tips
BEHAVIOR OF THE AMPLIFIER
- Defined and dynamic sound, from extreme clean to controlled crunch/distortion
- Modular EQ for body, brilliance and presence
- Adjustable tremolo for vintage or modern effect
- Modular gain to go from crunch to full distortion
Advice:
- Bright + Treble high → sharp sound for lead
- Middle medium-high → maintains body and presence
- Controlled bass → avoids muddying with high gain
- Speed and Depth → modulate the tremolo without altering the timbre
Final advice:
- High Gain + Treble/Presence → punchy lead sound
- Medium tremolo + moderate Speed → controlled vintage effect
- Master Vol + Output Level → adjust pressure without altering the tone
