In the past I had problems with a couple of Monster cables not fitting my 1/4 jacks of my Alembic Anniversary bass. I called Monster and discussed it with them. They were aware of the problem. They sent me double the cables back for my hassle (4), and I was satisfied with the results received. These days I generally use Monster Pro 1000 cable to my rack and throughout my rack now. Zero problems - happy camper - this is a pricy venture, though.
A couple of months ago I bought my friend a couple Monster 'Rock' cables off eBay for his birthday, to replace the ones his new puppy chewed into shreds. One came in with a dead end, so I called Monster (I would have to go along with Joey on no strain relief on these cheap cables - They are made well, but I was surprised when I opened the bad jack up and checked it out). I got some girl on the phone, Becky. She said they do not cover anything bought on eBay from non-authorized sellers. I told her OK, but if that was to be their attitude, I would have to stop using their products and they would lose a customer who has literally spent thousands on just cabling from them over the years. She that That fine.'
Wow, I am the nicest guy on the block until someone crosses the line with me. I went into bad customer mode and demanded her manager. She said she would connect me, but could not guarantee I would get him. Grrrrr . . . I ended up in his voice-mail, and was primed by them to rant his ear off. I left my number and went to their site to e-mail them. Before I could finish the e-mail the manger called, told me they were having a lot of problems on eBay with people and non-cable items, apologized countless times, and put two cables in the mail for me. A worker that says it is fine to lose a customer is one that does not want to keep their job long in this tight job market we live in. I hope Becky is doing fine at the yogurt shop or where ever she landed, as I could read in the manager's voice his displeasure in that bit of small talk she handed out.
Anyway . . . I'm still using Monster cables until I do end up with a serious problem with them. Then I will switch to another brand I have heard good things about (I have read a lot of good stuff about Mogami cables). Pro 1000 cables are a bit different than Monster's others. If you play with one, you will instantly know the difference, even just picking one up. Some people may not like such a heavy cable that is hard to 'kink' and is not 'rubber' coated. I like Zaolla cables, too, nice and thick and have a solid silver core, but the price has gone up with the price of silver, so Monster Pro 1000's are cheaper these days, and Zaolla does not make rack length cables, just instrument ones. Maybe when I am done with the Zaollas, I can sell them for scrap silver? OK, I'm done yakking . . .
