re: Good guitar practice combo amp

My Line 6 modeler has song-specific presets, which is really handy if you're wanting a fast greasy tone model without dialing a lotta knobs. The one I use to replicate my '90 Mark III halfstack is Line 6's "Still of the Night" by Whitesnake circa '87 preset.

John Sykes used a '86 Mark III Coliseum head atop a 4x12 to record the song, aka my Mark III with a higher wattage power section.

The Line 6 Spider I have replicates a Dual Rec in their gain options according to the manual, but the preset sounds and behaves under my hands like my Mark series. Perfect for the den when I don't want stage volume from my real deal amp. When I just want ... you guessed it ... a practice amp like the OP seeks.

Keep in mind, I have been Mesa-Boogie amplification for 30 years and I've owned virtually every incarnation of the Mark AND the Dual Rectifier during my tenure with the brand. I practically have these amps in my DNA.

One moron's opinion on a trash/garbage amp. Glad to contribute.
