So I just rented the Traynor Ironhorse amp (to see if it is worth buying). I must say I am pretty impressed with this little beast. Small light weight head, that is switchable to either 40 watts or 15 watts, with fx loop. A lot of features for a great price. I had it going into a 2 x 12 mesa cabinet for practice on Saturday, and this things is freaking loud. I was amazed at how much headroom I had on the 15 watt setting. I am pretty sure I am going to be buying this little beast.
