The Mustang LT25 lacks the JCM800's tight low-end and real tube compression, so the Metal 2000 model is the closest match for modern high-gain. Mid pushed to 6 compensates for the modeling's tendency to scoop; bass dropped to 5 keeps the low A from getting muddy through the small speaker. Gain at 8 reaches sufficient saturation without turning to fizz — the original used a tight-biased tube amp with an overdrive tightening the front end, which this amp cannot replicate.
