Think this will cause any problems? I got a yorkville xs400t. It has a tube head.. My speakers were pissing me off today, and I just got a 1/4 inch --> 1/8 inch converted for a mic I got today. So I used my bass cord and pluged into laptop, and amp and it sounds very good ( probably because of the 70 watt tweeter ). I am just wonderin' if this might cause any harm? Or just save me 150 bucks on new computer speakers.
