I think it's not secret I've done a fair share of music gear flipping...
And there's a lot of charities, and causes... and I regretfully have to say- I never liked anything I've seen out of them.
I'm always seeking gear, and sometimes- at the right price I can't say no.
About 4 years ago a chain of pawn shops had to get rid of excessive inventory- I realized this after seeing all the guitars at one shop for $25-30 worth 10x that, and then every other location started to call me.
They sold me 125 guitars at an average of $16.25 each. Most were new.
I put them in storage...
And over the years contacted numerous charities, all who had like 'sponsorships' with big brands etc... and I'm like 'listen...even wholesale you're paying 150-200 for these squiers and I don't buy that stuff but I find them for 20-30 all the time- whatever you're currently spending I can get you 8x the guitars for the money and I don't want to make money- I just want to pass on the good deals to people that can use it or kids that can't afford it"
I got so much bullshit it was astounding... it's all sponsors and corporations- mostly trying to look good and not actually help people or get their money to go further. Everything I saw first hand, I hated. And- I have to conclude it's really not about what they say it's about or want it to seem.
Even at concerts where they auction a guitar and the money goes to charity and the artist signs it- I've offered these people free guitars- with no promotion, no advertising, nothing in exchange- It's a simple act where I can take something new/mint I pay $20 and turn it into a lot more for a good cause and every single time- it's been bullshit, or fake bastards not taking me up on anything.
Oh so what happened to the 125 guitars?
I competitor of that pawn shop opened up their biggest store, went to check it out- they had no guitars
I asked "you got any guitars" they said "no we need some"
The same day I got a post card from my storage unit they were doubling the rate I prepaid for up til that time...
And then unloaded a storage locker of guitars on them. Twice.
So... sell me your gear/pedals or not- I think you're better off selling and doing something good with the money.
