Manufacturer Info
By combining Marshall valve tone with guitar-friendly MIDI technology, the JMP-1 establishes itself as the leading edge in rack mounted preamps. 4 custom-voiced channels are provided: Clean 1, for warm full bodied chords; Clean 2, for the glassy edge of a JTM45 and a spectrum of bright tones; OD1, for smoldering power and the searing tones of modern metal; and OD2, for tight, focused tone and all the sustain you could ever want. The JMP-1 has MIDI in, out, and thru connections plus a mapping facility. Also features a programmable stereo effects loop and Speaker-Emulated outputs (in addition to standard outputs), including an incredibly realistic stereo emulation.

I use quality boxes, thick bubble wrap, and peanuts to pack guitars. I have a very high rate of successful shipping (meaning few damaged instruments). I have been doing this 10 years and know how to pack well--with or without a hard case. I wrote a detailed story with photos on how I pack a guitar, which you can find on my StillKickinMusic site blog. If you Google "THERE IN ONE PIECE...How to Pack a Guitar" you will find it. Thanks.
