User Feedback:

Constructive criticism indicates that the humming noises and build quality has issues alongside other problems. The GP-1’s design and flexibility earn praise from most users as it facilitates quiet practice. Many people are also pleased to note that noise is not an issue versus the distortion tone that enthusiasts enjoy. It’s users that appreciate GP-1 the most. Positive comments stated that it is suitable for distortion tones and easy for beginners as well.
