“Thanks for continuing to strive for excellence in the many services you provide. The website looks great. The more streamlined look is less distracting and I think will make navigating the sight even better!

I have been using LMII as my main wood/parts supplier for almost 5 years now. LMII not only provides excellent products, but has been a link for me to gain access to a tremendous amount of expert knowledge and instruction on acoustic guitar building. Thanks for striving so hard to connect the dots for newer luthiers like myself to be able to benefit from the hard earned experience of the pros. I am now starting on my tenth guitar and have sold 6 of them. With each build, I strive to venture to new personal ground and it comforts me to know that LMII is always there and I can depend upon you guys for whatever I need, every step of the way."
