"The One".......................... Does it truly exist, or just a figment of our imagination :biggrin:
Good question. If I were making my living from the gear, then my IT systems experience echoes your concerns...what if it dies? If the cost of duplication is less than the lost revenue and downtime, then don't think twice and buy it. It's a wise insurance policy (and makes you really look pro if something fails in the middle of a job. That can guarantee a call-back.).
For us weekend warriors, it doesn't seem too reasonable to duplicate our gear, but even playing 30-40 gigs a year is a business commitment. If I couldn't play because of failed gear I'd be replaced in a heartbeat. Of course, it pays to buy reliable, professional equipment to begin with.
Not sure i'd duplicate equipment unless I was in a pro situation or had a lot of money. Even then i'd maybe only duplicate the amp. Guitars... i'd be happy to have a few Strats, different PRS's, etc... I just don't feel the need to have the exact same guitar with the same pups, etc. Amp wise, i'd want at least one identical backup on stage with me every night and perhaps identical rigs dotted across the world. Anyhoo... That's dream world, back to reality...
I love my Laney Lionheart. My only worry would be it getting stolen in a break in. It seems unlikely they would (Famous last words!!!) compared to other items in the house. Right now it would be easy enough to replace it. If they stopped manufacturing them and they rarely came up used then it could be a different story.
Were it me (and in my case, it is me!) I wouldn't back it up with the same thing. I know you were on the fence regarding the MDT early on, but I think that it's the perfect complement to the HXDA. If I recall, you were concerned with clean headroom, and initially, I was of the opinion that the MDT really didn't go very clean at reasonable gig volumes. That's just because I just didn't fiddle much with the Bright switch. Set in the "normal" configuration, master dimed, volume on 10 o'clock, it's clean heaven, with beaucoup de volume. Hit the bright switch in the configuration, and it goes from great clean to JTM45 crunch (which makes me wish that the bright switch could be foot switchable.).
It'll sound crazy, but I've settled on a gig configuration with the MDT set as the clean machine, and the HX/DA set as the dirty amp, both switched through a Radial Headbone into a single cab. Works fantastic...
