Electro-Harmonix 12AT7WCEH is a small plate design featuring low noise. Because of its low noise, Electro-Harmonix 12AT7WCEH is our go-to choice for reverb driver. If you are having problems with your amp's reverb hissing and whistling with a tired 12AT7, this tube is definitely worth a try.
Electro-Harmonix 12AAT7WCEH also excels as a phase inverter in any amp. 12AT7 and ECC81 refer to the same tube and Electro-Harmonix 12AT7WCEH can be used anywhere a 12AT7 or ECC81 is called for.
