I wasn't happy with my Strat sound through my Vox NT15c. It was a bit too bright/chimey and changing strings didn't seem to help. Being new to guitar when I bought the amp, I didn't know that Vox was known for their chime. I found the amp used for $200 out the door, and fell head over heels in love with it after hearing the overdrive/gain channel. My Gretsch sounds great through it as is so I didn't want to sell the amp or get a new one. I considered modding the Strat with different pickups but I've done mods on my bass guitars which were hit or miss (mostly miss), so I really wanted to avoid modding the strat. It just so happened that about a month or so ago I had to have a preamp tube/valve replaced and I noticed how much of a difference it made and, the difference it made depending on where the tube sat in the lineup. After much research I decided to buy all new tubes. I bought (2) Tung-Sol EL84 New Production Power Vacuum Tubes and (3) Electro-Harmonix 12AX7 Preamp Vacuum tubes, and the difference is like night and day. I can't put the Strat down now. I only stopped playing to take a break and decided to post these findings. If you're not getting the sound you're searching for, installing new tubes may be the answer. The original 2 EL84's just said China on the tube and the 3 12AX7's were mixed (1 China, 1 Ruby, and a JJ). TubeDepot had a sale on tubes and delivered the new ones in 3 days.
