I currently need a rack case for an Hartke 3500. My budget is around $150 AUD and would it be worth purchasing overseas? I will only need it to fit the 3500 head. I currently have a Hartke 3500 and a Hartke 410XL cab but was wondering if it worth purchasing a 115XL? Would it blow the amp up or would the amp supports that amount of wattage? How much more power would it add if I did buy the 115XL? Kind regards Joe.
